Hi all,
I am trying to interface a BLE mikrobus module onto a Yocto based Linux SBC. I need to use Zephyr's hci_uart example to flash it onto the module, the mikrobus BLE module is based on nrf52833dk. But it doesn't have a primary 32.678KHz crystal, so I need to use a secondary crystal. If anyone knows how to configure a secondary crystal in Zephyr for the hci_uart example and flash it onto the module, please help me out on this.
By making the following changes in prj.conf file in the hello world example
I tried it on the Hello world example to see if the module is able to print anything onto the console, nothing comes up on the console.
The message that I have received from the vendor of that is said "The module doesn't have 32.678KHz crystal, You need to select the secondary crystal. I mean the Internal RC Circuit".
I couldn't make much out of it. But that's what they said.
Thanks in advance.
